Photos unable to move/resize manually added face
I've been using Photos since iPhoto. I'm currently using 3.0 on High Sierra and have over 4,000 photos in an iCloud library.
I recently realised that when you add a face manually, you are meant to be able to resize and move the circle to identify the person. This isn't working for me and the circle is locked in its default position. When I try and drag the small dot on the circle (or anywhere), the photo behind is dragged instead of the circle.
I experienced this on 2 different machines with the same iCloud library (MacBook Pro and Mac Mini). I've read that other people experiencing this problem fixed it rebooting or reopening or repairing the library. I've tried them all, but nothing fixes it and the feature is broken.
